context_page_description: This is a list of atheists in science and technology. A mere statement by a person that he or she does not believe in God does not meet the criteria for inclusion on this list. Persons in this list are people who both have publicly identified themselves as atheists and whose atheism is relevant to their notable activities or public life.
context_section_description: Jacques Lacan (1901–1981): French psychoanalyst and psychiatrist who made prominent contributions to psychoanalysis and philosophy, and has been called "the most controversial psycho-analyst since Freud".
  Joseph Louis Lagrange (1736–1813): Italian mathematician and astronomer that made significant contributions to the fields of analysis, number theory, and both classical and celestial mechanics.
  Jérôme Lalande (1732–1807): French astronomer and writer.
  Lev Landau (1908–1968): Russian physicist. He received the 1962 Nobel Prize in Physics for his development of a mathematical theory of superfluidity.
  Alexander Langmuir (1910–1993): American epidemiologist. He is renowned for creating the Epidemic Intelligence Service.
  Pierre-Simon Laplace (1749–1827): French mathematician and astronomer whose work was pivotal to the development of mathematical astronomy, mathematics, physics and statistics, and anticipated the discovery of galaxies other than the Milky Way and the existence of black holes. Laplace formulated Laplace's equation, and pioneered the Laplace transform which appears in many branches of mathematical physics, a field that he took a leading role in forming. He restated and developed the nebular hypothesis of the origin of the Solar System. Laplace is remembered as one of the greatest scientists of all time. Sometimes referred to as the French Newton or Newton of France, he has been described as possessing a phenomenal natural mathematical faculty superior to that of any of his contemporaries.
  Paul Lauterbur (1929–2007): American chemist who shared the Nobel Prize in Physiology or Medicine in 2003 with Peter Mansfield for his work which made the development of magnetic resonance imaging (MRI) possible.
  Richard Leakey (1944–): Kenyan paleoanthropologist, conservationist, and politician.
  Félix Le Dantec (1869-1917): French biologist and philosopher of science, noted for his work on bacteria.
  Leon M. Lederman (1922–2018): American physicist who, along with Melvin Schwartz and Jack Steinberger, received the Nobel Prize for Physics in 1988 for their joint research on neutrinos.
  Jean-Marie Lehn (1939–): French chemist. He received the 1987 Nobel Prize in Chemistry, together with Donald Cram and Charles Pedersen.
  Sir John Leslie (1766–1832): Scottish mathematician and physicist best remembered for his research into heat; he was the first person to artificially produce ice, and gave the first modern account of capillary action.
  Nikolai Lobachevsky (1792–1856): Russian mathematician. Known for his works on hyperbolic geometry.
  Jacques Loeb (1859–1924): German-born American physiologist and biologist.
  H. Christopher Longuet-Higgins FRS (1923–2004): English theoretical chemist and a cognitive scientist.
